Apple only supported PPC for about 3 years after the Intel transition... what are you basing 5-6 years of support on? Apple hasn't made that promise. And what user that is ok with a 6 year old computer is interested in spending several thousand on a new macbook that they're going to have to throw out in 3 years? The only user I can imagine that would be ok with the 16" macbook are the users that upgrade every 2-3 years... they can risk it and likely won't lose out on anything except maybe the resale value.
